CEO Commentary
Stacy Kymes, President and CEO, stated, “We delivered another strong quarter, with $646 million of loan growth, 11.5% year-over-year loan growth, continued expansion in core net interest income, and peer-leading credit outcomes. Our disciplined approach to managing the balance sheet also helped us exit the quarter with top-quartile tangible common equity, despite a period of rapidly increasing interest rates.
These results are intentional, not accidental. They reflect decisions we have made consistently over many years around capital, liquidity, interest rate risk and credit. Higher rates created headwinds for mortgage banking and fixed-income trading this quarter, but we view those businesses through the cycle, where they provide an important source of diversification to our overall earnings profile.
We manage the company for the long term, not for any one quarter. That discipline, combined with the diversity of our franchise, positions us to deliver durable performance and continue serving our customers well across a wide range of operating environments."

Fees and commissions revenue totaled $188.0 million for the third quarter of 2026, decreasing $14.0 million compared to the prior quarter.
Brokerage and trading revenue decreased $13.0 million to $19.5 million, primarily driven by an unfavorable rate environment and lower fixed-income trading volumes during the quarter. The nearly 80 basis point increase in the 10-year Treasury yield reduced customer demand for fixed-income products and mortgage-related activity, resulting in lower transaction volumes and trading revenues.
Mortgage banking revenue decreased $2.2 million, driven by a decline in mortgage production volume and spreads due to rising mortgage interest rates. Production revenue as a percentage of production volume decreased 77 basis points to 0.06%.
Fiduciary and asset management revenue decreased $1.1 million, as the prior quarter benefited from seasonal tax preparation fees. Excluding this seasonal revenue, fiduciary and asset management revenue increased over the prior quarter.
Other gains, net, were a net gain of $5.7 million compared to a net gain of $42.4 million in the prior quarter. The second quarter of 2026 included a $30.9 million pre-tax gain, net of economic hedge, related to the exchange of our Visa B shares under the exchange offer by Visa, Inc. The current quarter included a net gain on investments related to deferred compensation of $1.8 million compared to a net gain of $8.8 million in the prior quarter.

Excluding the impact of deferred compensation, total operating expense increased $6.4 million.
Personnel costs increased $6.5 million excluding the impact of deferred compensation. Regular compensation expense increased $3.2 million, primarily reflecting investments in talent, including the addition of revenue-producing personnel. Cash-based incentive compensation increased $1.2 million due to strong loan production during the quarter. Employee benefits expense increased $1.1 million, driven by higher employee healthcare costs, partially offset by a seasonal decrease in payroll taxes.
Non-personnel expense was consistent with the prior quarter. A $2.6 million increase in data processing and communications expense, primarily driven by higher software costs, was fully offset by decreases in business promotion expense and net occupancy and equipment costs. Mortgage banking costs decreased $1.2 million due to lower loan payoff activity during the quarter.

Our healthcare sector loans primarily consist of $3.1 billion of loans for the development and operation of senior housing and care facilities, including independent living, assisted living, and skilled nursing. Generally, we loan to borrowers with a portfolio of multiple facilities, which serves to help diversify risks specific to a single facility.

No shares of common stock were repurchased during the third quarter of 2026. The company repurchased 2,519 shares of common stock at an average price of $129.89 per share in the second quarter of 2026.

Credit Quality

Excluding loans guaranteed by U.S. government agencies, nonperforming assets totaled $58 million, or 0.21% of outstanding loans and repossessed assets, at September 30, 2026, compared to $55 million, or 0.20%, at June 30, 2026.

No provision for expected credit losses was necessary for the third quarter of 2026. An improvement in economic forecast assumptions, primarily GDP growth and lower unemployment, compared to the prior quarter was offset by the impact of loan growth during the quarter.
At September 30, 2026, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $322 million, or 1.16% of outstanding loans and 555% of nonaccruing loans, excluding residential mortgage loans guaranteed by U.S. government agencies. At June 30, 2026, the combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $323 million, or 1.19% of outstanding loans and 592% of nonaccruing loans, excluding residential mortgage loans guaranteed by U.S. government agencies.

This news release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are based on management's beliefs, assumptions, current expectations, estimates and projections about BOK Financial Corporation, the financial services industry and the economy generally.

Management judgments relating to and discussion of the provision and allowance for credit losses, allowance for uncertain tax positions, accruals for loss contingencies and valuation of mortgage servicing rights involve judgments as to expected events and are inherently forward-looking statements.

BOK Financial Corporation Quarterly Earnings Release
Exhibit 99.1(b)
Explanation of Non-GAAP Measures
The tangible common equity ratio and return on average tangible common equity are primarily based on total shareholders' equity, which includes unrealized gains and losses on available-for-sale securities, less intangible assets and equity that do not benefit common shareholders. These measures are valuable indicators of a financial institution's capital strength since they eliminate intangible assets from shareholders' equity and retain the effect of unrealized losses on securities and other components of accumulated other comprehensive income in shareholders' equity.
The efficiency ratio and adjusted efficiency ratio measure the company's ability to use its assets and manage its liabilities effectively in the current period.
Pre-provision net revenue is a measure of revenue less expenses and is calculated before provision for credit losses and income tax expense. This financial measure is frequently used by investors and analysts and enables them to assess a company's ability to generate earnings to cover credit losses through a credit cycle. It also provides an additional basis for comparing the results of operations between periods by isolating the impact of the provision for credit losses, which can vary significantly between periods.
Net interest income and net interest margin excluding trading activities removes the effect of trading activities on these metrics allowing management and investors to assess the performance of the company's core lending and deposit activities without the associated volatility from trading activities.
We believe adjusting net income and earnings per share for notable non-core items enhances comparability of results with prior periods, demonstrates the impact of significant items, and provides a useful measure for determining the company's expenses that are core to our business operations and are expected to recur over time.

Yield calculations are shown on a tax-equivalent basis at the statutory federal and state rates for the periods presented. The yield calculations exclude security trades that have been recorded on trade date with no corresponding interest income and the unrealized gains and losses. The yield calculation also includes average loan balances for which the accrual of interest has been discontinued and are net of unearned income. Yield/rate calculations are generally based on the conventions that determine how interest income and expense is accrued.
